fix(ci): guard reviewed audit cache inputs

[prekshivyas]

Outcome

Protect the reviewed npm audit cache identity from target-controlled symbolic links, complete both Docker build contexts, and prove the audit receipt handoff at the production verifier boundary.

Reason

This follow-up closes the remaining review gaps from PR #11069 without changing the reviewed npm policy or supported user behavior.

Related issues

Follow-up to #11069.

Changes

• Use one shared, symlink-safe repository input resolver for audit production and cache identity.
• Stage that resolver in every trusted sparse checkout that executes the audit producer.
• Verify that both legacy and optimized sandbox build contexts stage the reviewed npm audit policy files with mode 0644.
• Exercise a receipt emitted by the real audit producer through the production verifier, including a rejected npm-version mismatch.
• Reject the removed --raw-copy option before publishing either verifier output.
• Keep raw-report copying in the Docker consumer after receipt verification succeeds.

Verification

• Focused audit, receipt, sparse-checkout, workflow, build-context, and supply-chain tests: passed.
• Trusted sparse-checkout producer imports: 13 passed, covering all 12 workflow checkouts plus the producer-to-verifier handoff.
• Final merge validation: 155 tests passed; 54 platform-only tests skipped.
• Codebase growth guardrails: 45 passed.
• Source-shape ratchet: passed at zero cases.
• Repository checks and CLI type-check: passed.
• Normal PR CI: passed, including all 12 CLI shards.
• Managed-image CI: passed, including direct Hermes startup, both OpenClaw MCP discovery passes, and exact all-agent managed runtime activation.
• PR Review Advisor: passed; all nine specialists reported no issue requiring a change.
• CodeRabbit and CodeQL: passed.
• Commit df0f8413d is verified and includes the DCO declaration.
• Independent documentation review of commit df0f8413d: passed; no documentation change needed.
• Secret review: the diff contains no credentials, API keys, or secret values.

Review notes

The branch merges current main commit 37cedc990; conflict resolution was mechanical and did not change the effective PR patch. The dynamic Bash test command flagged by CodeQL was removed. The executable handoff test uses the real audit producer and production receipt verifier, and each trusted sparse checkout now proves that the producer and all direct imports load together.

📝 Walkthrough

Walkthrough

The change centralizes repository input-path validation, removes raw audit report copying from receipt verification, updates trusted sparse checkouts, consolidates sandbox policy staging, and adds workflow, receipt, security, and regression tests.

Docker copies the cached report after verification. Tests cover rejected arguments, receipt metadata mismatches, retained artifacts, and command ordering.
Sandbox audit policy staging src/lib/sandbox/build-context.ts, test/runtime/sandbox/sandbox-build-context.test.ts	Optimized and legacy build-context flows use shared staging logic for both audit policy files. Tests verify file contents and mode 644.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to df0f8

The audit hardening behavior is not validated through the Docker build path, so a future regression in receipt failure handling or raw-report handoff ordering could pass these tests. Add behavioral build-level coverage before merge.

Test the Docker build behavior instead of Dockerfile text.

These assertions fail for safe refactors and do not prove the build boundary behavior.

• test/security/mcporter-supply-chain.test.ts#L227-L227: verify that a build with a removed --raw-copy invocation fails before output publication.
• test/security/mcporter-supply-chain.test.ts#L242-L244: verify that an invalid receipt prevents raw-report handoff and a valid receipt permits it.

As per path instructions, tests must prefer observable outcomes through the public boundary over source-text assertions.

Approve on df0f841.

The shared resolver rejects traversal and symbolic-link inputs before cache identity or audit reads. Trusted sparse checkouts include the new dependency. Receipt verification completes before Docker copies the raw report. Both build-context paths stage the reviewed audit policy with mode 0644.

All required GitHub checks are satisfied for this commit. The changes check is skipped after the base advanced, and gh pr checks --required returns success. GitHub reports the PR mergeable with no conflict. DCO and all 10 verified commits pass. I reviewed the complete diff, the resolved review thread, the full nine-specialist Advisor output, and all nine security categories. No blocking defect remains.

[non-blocking] CodeRabbit suggested a Docker build behavior test that would make the receipt-to-copy ordering less sensitive to source-text refactors. A focused follow-up PR can add one invalid-receipt build case and one valid-receipt case. This does not block the current change because the producer/verifier handoff tests and current managed-image CI cover the active boundary.
